    • A temperature-sensitive label includes a container provided with means for the application on an item to be monitored and housing a temperature-sensitive system made up of a filiform shape memory member (1) restrained to a filiform bias member (2) provided with an engaging seat (3), formed by bending it back at one of its ends, in which one of the ends of the filiform shape memory member (1) is introduced in such a way that in case of exposure to a temperature lower than a preset critical threshold temperature (T c ) the filiform shape memory member (1) performs a phase transition, from austenitic phase to martensitic phase, which causes its irreversible disengagement from the restraint formed by the engaging seat (3) and said disengagement condition is visible through a transparent window (5).
    • 温度敏感标签包括容器,该容器设置有用于待监测项目上的应用的装置,并且容纳由限制到丝网状偏置构件(2)的丝状形状记忆构件(1)构成的温度敏感系统, 接合座(3)通过在其端部之一弯曲而形成,其中丝状形状记忆构件(1)的端部之一被引入,使得在暴露于低于预设的温度的情况下 丝状形状记忆部件(1)的临界阈值温度(Tc)从奥氏体相到马氏体相进行相变,这导致其不可逆脱离由接合座(3)形成的约束,并且所述分离条件通过 透明窗(5)。
